Why were they slaughtering zombies like it was a game at the beginning of the episode, but then they are suddenly afraid of zombies again by the end of the episode?
I think because of the close quarters within the jail.
A spear-like weapon with a bar after the blade to stop it from going in all the way and getting stuck would be a great weapon. I think there was a medieval weapon called a bec de corbin that would do the trick. I think T-Dog had a fireplace poker that was similar, but way too short for my tastes.
